当PHP中的tempnam()函数被禁用后的应对策略与解决方案

PHP代码:

---


// write to tmp file, then rename it to avoid
// file locking race condition
$_tmp_file = tempnam($_dirname, ‘wrt’);
if (!($fd = @fopen($_tmp_file, ‘wb’))) {
$_tmp_file = $_dirname . DIRECTORY_SEPARATOR . uniqid(‘wrt’);
if (!($fd = @fopen($_tmp_file, ‘wb’))) {
$smarty->trigger_error(“problem writing temporary file ‘$_tmp_file'”);
return false;
}
}
fwrite($fd, $params[‘contents’]);
fclose($fd);
